If you’re booked on Anthem of the Seas, the newest Royal Caribbean ship on the sea, make sure you take a ride on the North Star. That’s the pod at the end of an arm that takes you on a ride over the water while the ship is cruising. And after you’ve done it, do it again. And again. And again.

If you are a cruise aficionado who can’t wait to see Harmony of the Seas, the next new Royal Caribbean ship that’s due in 2016, go on its North Star, too. Then go again. And again. And again.

If you think you might like simulated sky diving, RipCord by iFly is available (or will be) on both those Quantum Class ships, so don’t miss a chance to give it a shot. Then do it again. And again.

Both those thrill features are free.

For now.

The flagship for this class is Quantum of the Seas. It is cruising in Asia, home-ported in Singapore. If you go on that North Star, it costs $20. If you go on that RipCord, it costs $26 for the one-minute ride.
